+//
+//   b-i-v              — Video endpoint declaration. Tells the UAS Tool where
+//                        to pull the RTSP stream for this drone.
+//
+//   b-m-p-s-p-loc      — Sensor position event. Carries the camera azimuth,
+//                        field-of-view, and slant-range that the UAS Tool uses
+//                        to draw the FOV cone on the map and to project AR
+//                        markers onto the video feed.
+//
+// The two events are linked: the b-m-p-s-p-loc detail contains
+//   <__video uid="<drone-uuid>"/>
+// which references the uid of the b-i-v event, so the UAS Tool knows which
+// video stream belongs to this sensor.
